Follow up the removal of .vscode/.
- Ignore .vscode/ except extensions.json, as the other sites do
- Remove the README paragraph describing .vscode/settings.json
react-router-dom stops at 7; version 8 ships only as react-router,
which the other archived sites already use.
- import the router from react-router instead of react-router-dom
- update React, Vite, three.js types, Biome and CSpell
- keep @types/node on the 24.x line with .ncurc.js
The README still described the Create React App scaffold and mixed
the release history into the same file.
- Document the current stack, requirements, project structure,
routes, data model, and build output
- Move the release history to CHANGELOG.md and add entries for
3.0.0, 3.0.1, and 3.0.2
Replace Create React App scripts with Vite equivalents.
Removes npm start, npm test, and npm run eject. Adds
npm run dev, npm run preview, npm run lint, npm run format,
and npm run format:check. Updates links to Vite and React docs.
